Mechanism for cutting a thread reserve of spindles in continuous spinning machines

Abstract

A mechanism for cutting a reserve of thread of spindles of continuous spinning machines has a cutting blade, an element which is draggable and which is adjustable without contacting an area of a spindle where there exists a thread of a reserve to be cut and removed, and a device for regulating an adjustment of the element.

What is claimed is:  
     
       1. A mechanism for cutting a reserve of thread of spindles of continuous spinning machines, comprising an element which is draggable and which is adjustable without contacting an area of a spindle where there exists a thread of a reserve to be cut and removed; means for regulating an adjustment of said element; and a screen-like element partly confined to a lower area of a spindle, said regulating means including a guiding element which contacts said screen-like element, copying thus exactly a position of each spindle, and locating itself at the position which secures a correct adjustment between said element and said area of the spindle where is located the thread of the reserve to be removed. 
     
     
       2. A mechanism as defined in  claim 1 , wherein said element is formed as a cylinder-shaped element. 
     
     
       3. A mechanism as defined in  claim 1 , wherein said element is formed as an element selected from the group consisting of an element composed of steel, an element coated with a slightly abrasive material, an element composed of metal with a final superficial treatment, and an element composed of a non metallic material. 
     
     
       4. A mechanism as defined in  claim 1 , wherein said element is freely rotatable about its vertical axis. 
     
     
       5. A mechanism as defined in  claim 1 , wherein said regulating means include an element selected from the group consisting of a spring, an element exerting a pressure, a roller element, a guiding bearing, fastening parts, and a support fixed on a frame of a cleaning element which is fixed on dragging means. 
     
     
       6. A mechanism as defined in  claim 1 , wherein said regulating means include an element exerting a pressure. 
     
     
       7. A mechanism as defined in  claim 1 , wherein said regulating means include a guiding element formed to directly and tangentially contact an outline of a lower area of a spindle thus copying a part of the outline which forms a continuation of a top part on which a thread of the spindle to be cut and cleaned is fixed. 
     
     
       8. A mechanism for cutting a reserve of thread of spindles of continuous spinning machines, comprising an element which is draggable and which is adjustable without contacting an area of a spindle where there exists a thread of a reserve to be cut and removed; means for regulating an adjustment of said element; a spring element which is not pressing when it is not located in front of any spindle; and a bearing adapted to contact a spindle or equivalent element so that said spring element and a relation of movement between different elements of the mechanism, and an actual axis and a sham axis coincide, the mechanism remains fully parallel to the axis so that said element copies an accurate position of each spindle by directly contacting the spindle or an equivalent element which has an accurate and concrete position with respect to related spindle. 
     
     
       9. A mechanism for cutting a reserve of thread of spindles of continuous spinning machines, comprising an element which is draggable and which is adjustable without contacting an area of a spindle where there exists a thread of a reserve to be cut and removed; means for regulating an adjustment of said element; guideways supporting said mechanism; and a mechanism for recovering a vertical position when spindles of the machine can be slightly out of alignment with each other and also said guideways supporting said element, said mechanism for recovering the vertical position being located close to said element. 
     
     
       10. A mechanism for cutting a reserve of thread of spindles of continuous spinning machines, comprising an element which is draggable and which is adjustable without contacting an area of a spindle where there exists a thread of a reserve to be cut and removed; and means for regulating an adjustment of said element, wherein said element is operative for adapting a 120° triangular wing shape with ends forming cylinders which take a shape of a spindle or an equivalent element, so as to carry out copying, said triangular cleaning mechanism rotating about a point and movable forward so that it is displaceable along the machine for cleaning a reserve of each of the spindles of a row. 
     
     
       11. A mechanism for cutting a reserve of thread of spindles of continuous spinning machines, comprising an element which is draggable and which is adjustable without contacting an area of a spindle where there exists a thread of a reserve to be cut and removed; means for regulating an adjustment of said element; and a substantially half-arched-shaped part formed by two parts for simultaneously cleaning several spindles, including one part for cleaning a spindle which is equivalent to the one part and another part which is equivalent to a bearing for copying a position of the spindle or an equivalent element, so as to position the mechanism with respect to the spindle and to take its shape. 
     
     
       12. A mechanism as defined in  claim 11 , and further comprising a common shape to which said half-arch-shaped parts are fixed so that they together can move forward the spindle for copying a position of the spindle, and also are rotatable apart from the spindle, to allow movement a step forward and cleaning of a following group of spindles.
